Want to replace my SRH840 pads

I love the SRH840s, the only thing that i think is meh is the pleather ear pads. I would love to put on the Beyerdynamic ones but I am fairly confident that these will not fit on my 840s. I hope that I am incorrect.

Should I look into getting different pads? Or should I think about modding it myself with socks or something? (Really have no idea what to do, just do not like the pads)
